Traumatic pseudolipoma: herniation of buccal fat pad, a report of two cases.

Traumatic pseudolipoma is a term used to describe intra-oral herniation of the buccal fat pad. A tear of the buccinator muscle and buccal mucosa allows the buccal fat pad to extrude into the oral cavity. Initially, the lesion can suggest a more sinister cause, but a history of trauma, an absence of mass before the accident, anatomical site and fatty appearance should suggest a diagnosis of traumatic herniation of buccal fat pad. This injury is rare, but two cases presented to the authors' hospital over a period of 3 months.
